Wow, 4 pounds, that was somewhat more than I am hoping for, but it's like you're saying, suddenly the weight adds up, and the plane is 20% heavier than expected..[:'(] But the good news are that your plane still flies good with this weight, and that is great news for me in case I'm not reaching my goal weight... How big is your F-35? How is it constructed? I saw a picture of it on your gallery, must say it looked good! [sm=thumbup.gif]
